Salmon today told MMAjunkie.com (www.mmajunkie.com) that he accepted the bout — at a catch-weight of 190 pounds — over the weekend.

“A Night of Combat II” features a handful of Xtreme Couture notables, including Jay Hieron, Mike Pyle, John Alessio and Haynes.

The event, promoted by Kim Couture’s KC Concepts and Scott Kelp of Superfights MMA, takes place at the Thomas & Mack Center in Sin City.

As MMAjunkie.com recently reported, company executives said the event will air on HDNet on approximately a one-week delay.

Haynes, who scored multiple upsets to make it to the “TUF 3″ championship fight, eventually lost to Michael Bisping at the show’s live finale in June 2006. He fought twice more in the UFC — in tough-fought losses to Rory Singer and Luke Cummo — before leaving the organization. He’s since won three of five fights, which included a unanimous-decision victory over notable Leopoldo Serao at a February IFL event.

Salmon, meanwhile, recently returned from what turned out to be a 10-month medical suspension from the California State Athletic Commission following a knockout loss to Jorge Santiago at a November 2007 Strikeforce show. Salmon has won four of his past five fights (all via TKO) — and six of his past eight fights since suffering losses to Rashad Evans and Alan Belcher in the UFC.

Salmon fought just a little more than two weeks ago and defeated NAAFS middleweight champ Mitch Whitesel at an event in his hometown of Columbus, Ohio.

The original “Night of Combat” took place in June. The combination MMA/boxing card drew 10,000 spectators and featured a main event of Alessio vs. Pete Spratt. Couture made her professional debut in the co-main event and suffered a unanimous-decision loss to Kim Rose.

“A Night of Combat II” will feature an all-MMA fight card, which includes:

UFC women’s bantamweight champion Ronda Rousey is probably the greatest female fighter on the planet, which is a tremendous feat. So why are we seemingly so obsessed with arguing about whether she could beat up men?
